PELCO® NanoXact and BioPure
Gold and Silica Shell Gold Colloid

Nanoparticles Developed for Ted Pella, Inc.

Tannic acid is a multidentate capping agent that can be displaced with many thiol containing ligands. As a general rule, tannic acid coated nanoparticles are more stable at high particle concentrations, while citrate capped nanoparticles are more stable in higher ionic strength solutions. Tannic acid capped particles are suspended in water.

The PELCO ® NanoXact and BioPure gold colloids (nanoparticles) are extensively characterized (see Technical Data below) and designed to meet the rigorous research demands in today’s market. They range in size from 5 to 100nm.

The gold colloids come with comprehensive specification sheets that provide all of the physical and optical characterization data necessary to integrate the nanoparticles into Surface Enhanced Raman Spectroscopy (SERS), plasmonic and photonic applications.
